Yes, the ACE KDC for group communication [1] and especially the ACE 
Group Manager for Group OSCORE [2] now use (the Labels of) COSE Header 
Parameters as values for the 'pub_key_enc' parameter.

This parameter indicates the format of public keys used in the group. 
The possible formats include also CWT/UCCS under pending registration; 
see for instance the paragraphs about 'pub_key_enc' in Sections 6.1 and 
6.4 of [2].

Best,
